IMPROVEMENT lN RESERVOIR COOKlNG-STOVES.

Specification forming part of Letters Patent No. 159,259, dated February 2, 1875; application filed December 30, 1874.

To all whom it may concern:

Be it known that I, JOHN H. GOODFELLOW, of Troy, in the county of Bensselaer and in the State of New York, have invented certain new and useful Improvements in Reservoir Cooking-Stoves; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 is a plan view of the upper side of a stove containing my improvements, a portion of the top plate being removed to show the arrangement of lines beneath. Fig. 2 is a vertical section of the same upon line 00 00 of Fig. 1. Fig. 3 is alike View of said stove upon line 2 z of said figure. Fig. 4 is a plan view of the upper side of a stove containing a modification of my,invention; and Figs. 5 and 6 are sections of the same upon lines as w and z 2 respectively.

Letters of like name and kind refer to like parts in each of the figures.

The design of my invention is to enable the contents of a water-reservoir to be heated by means of the surplus heat which is contained within various portions of a cooking-stove and it consists, principally, in a cooking-stove provided at its rear end with an inoased water-reservoir, and having a flue which communicates at one end with the external air, and at its opposite end with the reservoir-casing, and permits air to become heated and brought into direct contact with the ends of said reservoir, substantially as and for the purpose hereinafter specified It consists, further, in a flue that communicates with the open air at one end and with the reservoir-chamber at its 0pposite end, and which passes through and forms a part of the upper portion of the oven, substantially as and for the purpose hereinafter shown. It consists, further, in the arrangement of the flues that extend between the oven and reservoir-chamber, by means of which heated air from the former is permitted to pass into the latter and impinge directly against the ends of the reservoir, substantially as and for the purpose hereinafter set forth. It consists, further, in a cooking-stove provided with an incased reservoir, which latter is heated by external air, that is admitted to its ends by means of a flue, and afterward escapes into the usual exit-flue of said stove through an opening made by the removal of a portion of the rear end plate, substantially as and for the purpose hereinafter shown and described.

In the annexed drawings, A represents the top plate, B the bottom plate, 0 the front plate, D the rear plate, and E and E the side plates, of a stove, which is provided with a fuel-chamber, F, ash-pit G, oven H, and the usual system of flues. At the rear end of the stove is secured a casing, I, which is open at its upper side, and forms a chamber, K, that receives and contains a water-reservoir, L, the latter being preferably suspended from the rearward-extended top plate, A, which forms an ornamental finish for the upper end of said casing. Between the oven H and the top flue, M, and fuel-chamber F is formed a flue, N, which extends from the rear side of said oven forward to the front plate, 0, and communioates with the open air through suitable openings n n at each side of the stove, and, if desired, an opening, a, at its front end. Immediately above the oven H the flue N is divided into three parts by two vertical flue-strips, N and N, which extend from points near the back oven-plate, h, forward to the downward curve of the top of said oven, and thence laterally outward in opposite directions to the side plates, E and E. At or near the forward end of each side flue, N, is an opening, a, which extends into the oven H, and furnishes communication between the latter, through said flues, and the exterior air, while from each of the rear upper corners of said oven a flue, 0, extends rearward through the descending flue Pinto the chamber K of the reservoircasing, and enables communication to be effected between said chamber and oven. The front side of the reservoirL fits closely against the rear plate, D, while its bottom extends to the bottom of the chamber K, leaving a space only between the rear sides and ends of said reservoir and the casing I. At the transverse center of the chamber K the bottom of the casing I is depressed, so as to form a pit, 70, that extends from front to rear, and at its front end communicates with the ascending or exit flue Q through an opening, q, that is provided in the rear wall of the same. 7

As thus constructed the operation of my stove is as follows: Air from without the stove enters into the flue N through the openings n or a, and passes rearward to the end of the oven; from thence forward through the flues N and N, and openings 12. and a, into said oven; from thence, after circulation, said air passes rearward through the fines O and 0, against the ends of the reservoir L, and, after having circulated through the chamber K, escapes through the opening q into the exitflue.

It is found that during the passage of air through the tines N and N it takes up from the plates which form said fines a large percentage of their heat, and conveys the same to the oven, from whence, after giving off a sufficient proportion of such heat to raise the temperature of said oven to the necessary point, said heated air passes rearward, and, impinging directly against the ends of the reservoir, imparts a large percentage of its heat to the liquid contents of the same, after which, by circulation within the chamber K and the pit 7c, the remaining available portion of its heat is given off to said reservoir, such operation being effective in both heating and ventilating said oven, and in heating the contents of said reservoir.

For the purpose of controlling the circulation of air, the inlet-openings n a and a, and the exit-opening q, are preferably provided with dampers, which may be opened or closed at will.

In Figs. 4, 5, and 6 is shown a modification of my invention, in which air is admitted to the front portion of the flue N from beneath the stove, and to its upper portion through a snpplei'nentary flue or heating-chamber, N, which latter is formed beneath the center piece, and communicates with said flue N by means of an intermediate pipe, N.

From the oven H the heated air passes to the center and lower side of the chamber K, and from thence escapes into the exit-flue Q from a point near the upper portion of said chamber.

The exit-opening q is dampered, and the casing I of the reservoir extended above the top plate, A, so as to permit of the placing of dampered openings 13 i, &o., in the front side of such extended portion.

As thus arranged, by closing the exit-opening q and unclosing the openings 6 i, 850., the current of heated air, after having performed its principal office, may be caused to pass outward into and assist in heating the room.

Having thus fully set forth the nature and merits of my invention, what I claim as new 1s-- 1. In combination with the incased waterreservoir L, attached to or upon the rear end of a cooking-stove, the flue -N, N, and O, which communicates at one end with the outer air, and at its opposite end with the reservoircasing, and permits air to become heated and brought into direct contact with the ends of said reservoir, substantially as and for the purpose specified.

2. In combination with the oven H, the fines N and N, which communicate with the outer air and with the upper portion of said oven, and the flue O, which extends between the rear part of said oven and the chamber K of the reservoir-casin g, said parts being arranged to operate in the manner and for the purpose substantially as shown.

3. In combination with the oven H, and with the reservoir-chamber K, the flues O and O, which extend between the same, and permit heated air from said oven to be brought into direct contact with the ends of the reservoir L, substantially as and for the purpose set forth.

4:. In combination with the incased waterreservoir L, arranged upon the rear end of a cooking-stove, and with a flue for heating and conveying external air to the casing of said reservoir, the opening q, formed in and through the rear plate of the stove, and affording communication between said reservoir-casing and the exit-flue Q, substantially as and for the purpose shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this 30th day of December, 1874.

JOHN H. GOODFELLOW.
